I had an interview for Des Moines University last friday. The students and faculty were great, and alot of the facilities were new and state-of-the-art. The campus is very safe and living in Des Moines is affordable (one can get a one bed room apt for around $500-$600 and a two bed room apt. for $700-$900, depending on the location).
Des Moines is best described as a large city with a small city atmosphere. I mean, there is a deer crossing on one of the major streets (on MLK drive, I believe) and my friend and I saw turkery's at one of its park. If you like being in nature, I think Des Moines is a great town.
On the downside, if you're a persons craving a night life, Des Moines is a little bit lacking on that department--at least according to what I saw on Friday night. I went down town with my friend to look for excellent dining, and found that hardly anyone was there that night. It could be that I was at the wrong part of down town since the majority of buildings I saw that night were business offices, which are closed for the weekend anyways. Also, since you'll be in medical school, you probably don't want much of a night life at all.
Nevertheless, I loved Des Moines. If I were accepted, it'd to be a tough choice between DMU and KCUMB (which I just got accepted). I hope this helps. 😀
